The lamp for David's sake
Pattern
God promises David a house and a throne established for ever. Through the kings that follow, Judah is spared again and again for David's sake, so that his lamp is not put out in Jerusalem. The scroll of Kings ends with the line alive at a table in Babylon, and Luke gives the throne of his father David to Jesus.
Every northern dynasty in Kings is cut off on schedule, while Judah's one dynasty survives every wicked king it produces, and the text says why in one repeated phrase. The lamp promise is the engine of two books, and the New Testament states where it lands. A reader who follows the phrase follows the plot.
The covenant with David
Thy throne shall be established for ever.
A light alway in Jerusalem
One tribe kept for Solomon's son, that David my servant may have a light alway before me.
A lamp under a bad king
For David's sake did the LORD give him a lamp in Jerusalem.
Judah spared for David's sake
The LORD would not destroy Judah for David his servant's sake, as he promised him to give him alway a light.
The city defended for David's sake
I will defend this city, for mine own sake, and for my servant David's sake.

The line alive in Babylon
